We have specialized in Industrial Fasteners such as Bolts, Nuts and Screws since the establishment in 1927 and have grown as the leading supplier and exporter.  Meanwhile we have consecutively been awarded by Ministry of International Trade and Industry in recognition of development of our export business.

To cope with the increasing demand in domestic and overseas markets, we heavily stock a full range of fasteners from small size to large size ones (over 150 mm dia.) which are used for big plants in wide fields such as engineering, shipbuilding, harbor works, building industry, electric power companies, etc..  The volume and variety of our stock of fasteners really rank first in Japan.
Furthermore, to speed up making delivery, our inventory control is completely under the automated warehousing.
